Multi-chip package system

Abstract

A multi-chip package system includes a signal transmission line commonly coupled to a plurality of semiconductor chips to transfer data to/from the semiconductor chips from/to outside; and a termination controller suitable for detecting a loading value of the signal transmission line and controlling a termination operation on the signal transmission line based on the loading value.
